Answer:
slope is 2
Step-by-step explanation:
first add -14x like...
-14x+7y=-9
+14x +14x
7y=14x-9
divide 7 by the who equation
7y=14x-9
/7
y=2x-9/7
Answer:
60
Step-by-step explanation:
to find w:
sin(44) = w/30
w = 30sin(44)
w = 20.8 to 1 decimal place
to find x;
cos(x) = 20.8/45
x = 
(20.8/45)
x = 62.46940334
x = 60
Answer:
Four
Step-by-step explanation:
Let's expand and see how many nonzero terms:
⇒ (x+4)(2x²+3x+9)-3(x³-2x²+7x)=
⇒ 2x³ + 3x² + 9x + 8x² + 12 + 36 - 3x³ + 6 x² - 21 x=
⇒ - x³ + 17x² - 12x + 12
As we see the expression has four nonzero terms
